Your Undercarriage Options





Undercarriage: It’s the workhorse that pushes your dozer, excavator or track loader to get the job done — but it can also be a major cost driver. Did you know undercarriage typically represents 50 percent of a machine’s owning and operating costs? That’s why it pays to invest in a system that delivers the most value on your equipment AND in your specific application.



Why Cat® Undercarriage?

Lots of companies manufacture undercarriage, but there’s a reason — four of them, actually — that Cat® undercarriage is the best choice for your Cat equipment.


Designed for your machine

Because we design and manufacture our own undercarriage (the only OEM to do so), every component meets strict specifications for quality, durability and reliability — lowering your downtime and your operating costs.


Designed for your application

Our engineers understand how different conditions affect undercarriage in different ways. They design each Cat undercarriage option as a solution, built to take on the specific conditions you’re facing — from sand and gravel to mud and clay.


Proven performance

We factory and field test every Cat undercarriage system — and those tests show our undercarriage delivers up to twice the life of other brands.


Best return on investment

Longer wear life, lower cost per hour and the industry’s best undercarriage assurance program combine for a positive effect on your bottom line.



Undercarriage choices for construction

From small landscaping projects to big site-clearing jobs, there’s a Cat undercarriage option designed specifically for your work.


Cat Abrasion™

Our newest undercarriage, Cat Abrasion™, replaces SystemOne™ and comes with design improvements that deliver 50 percent longer life in your high-abrasion, low- to medium-impact applications.


Heavy Duty Extended Life (HDXL) with DuraLink™

Working in medium-abrasion, high-impact conditions? HDXL provides exceptional wear life and a lower cost per hour than other undercarriage brands.


General Duty

For your light-duty, low- to moderate-impact earthmoving jobs, General Duty is the most affordable undercarriage designed and manufactured by Caterpillar.


Rubber Track

Sometimes, steel isn’t the best choice. Cat rubber tracks improve traction, reduce machine wear and increase operator efficiency — and you can customize them to your work and terrain.
